Joey:
Why a choice those
specific two CPTs? I ask, because if you're interested in laser-anything, how about something that identifies and illuminates problems in your stroke (e.g. hitches, corkscrewing, et al.)?
Take a gander at the LaserStroke:
http://laserstroke.com/
I have one, and anytime I'm working on my fundamentals, or if I've had a bad set / bad showing in a tournament, etc., and I want to identify anything wrong with my cue delivery, I'll break this out and play with it on my cue for a bit. I can't tell you how many times I'd discovered I was doing something in my stroke (e.g. slight imperfections in my grip that introduce yaw in my stroke), I fix it, and I feel a bit better that I at least identified the problem.
(I don't do the "spot on the wall" method that they show in the video -- I don't like the idea of marking my wall. Instead, I'll practice where I'll line-up the vertical laser line on one of the vertical lines in the grid on the hanging calendar on the far wall, and stroke through trying to keep that vertical laser line lined-up without variance or rotation. It's very challenging!)
Thoughts?
